Multi Arms Borehole Caliper Tool 4Arms Borehole Diameter Logging System Uncased And Cased Hole Caliper System Geotechnical Borehole Caliper Logging Equipment
The Borehole Caliper Tool is capable of logging both uncased and cased holes, making it suitable for a wide range of applications. In uncased holes, it provides valuable information about the borehole diameter, which is essential for well planning, casing design, and geotechnical assessments. In cased holes, the tool enables the evaluation of casing integrity by measuring the internal diameter and detecting any deformations or obstructions.
The Borehole Caliper Tool is designed to withstand the harsh downhole conditions encountered during logging operations. It is built with robust materials and is resistant to high temperatures, pressures, and vibrations. This durability ensures reliable and accurate measurements even in challenging drilling environments.
The measuring probes underground are totally digitized.
The measuring probes underground are stainless steel materials.
Equipped with a automatic cabling winch.
The caliper/inclinometer measuring probe and sediment/inclinometer measuring probe become one. Convenient to operate.
The hole diameter measuring bias reduces to 5mm.
The control case adopts industrial computer, it is easy to operate and has strong anti-interference ability, it also can judge the model of the probe underground automatically.

(1) GDC-1EG control case takes IPC as main part, it is a SCM-core device for power suppling, signal collecting and data processing. It is composed of power module, RS485 serial port, SCM control circuit and counting circuit. The circuit is shown as
(2) The power module mainly convert the 220V AC supply to stable DC supply for this system and the probe underground. It output +24V, +12V and +5V three groups of DC supply
(3) The RS485 serial port achieves the communication between the measuring probe underground and SCM. It transmits the test result and orders and parameters sent by the machine.
(4) The SCM control circuit completes the collection for measurement data and measurement depth, sends orders and parameters and transmits the result to the notebook PC.
(5) The counting circuit completes the conversion of depth measurement and supply it to SCM control circuit.
(6) RS232 serial port is used to connect the control case and notebook PC to achieve the communication between the SCM and the notebook PC.
The Multi Arms Borehole Caliper Tool is a versatile logging system that provides accurate and comprehensive measurements of borehole diameters in both uncased and cased holes. It plays a crucial role in geotechnical assessments, well integrity evaluations, and borehole characterization. With its robust design, comprehensive coverage, and reliable measurements, the Borehole Caliper Tool is an essential piece of equipment for geologists, engineers, and drilling professionals involved in subsurface evaluations and wellbore integrity assessments.
